Myasthenia gravis (MG) is an autoimmune disease of the neuromuscular junction characterized by the fluctuating weakness of certain skeletal muscle groups. The use of intravenous immune globulin
a. increases anxiety and depression.
b. reduces the production of acetylcholine antibodies.
c. removes the antibodies produced by the autoimmune response.
d. increases the production of acetylcholine antibodies.
Question 2Infections are common acute conditions that demand prompt attention. A variety of factors can be responsible for the high risk of infection in the elderly.
Gerontological nurses should suspect an infection when which of the following phenomena occurs? A) The patient displays reduced activity and lowered resistance.
B) Embolus and thrombus are diagnosed.
C) A lower body temperature causes atypical fever.
D) Any abrupt, unexplained change in physical or mental function is detected.
Question 3In the aging process, older adults are able to
a. react to events immediately.
b. master new material quickly.
c. remember information from the immediate present (short-term memory).
d. learn new skills.
Question 4Despite the nurses' high-quality care and conscientious application of the principles of asepsis, a 78-year-old post-coronary bypass patient has developed an infection in his leg incision.
Which of the following factors may have contributed to the man's infection? A) Altered antigenantibody response
B) Decreased intracellular fluid volume
C) Decreased cardiac output
D) An adverse drug reaction
Question 5A 64-year-old man has sought care because of recent lower leg pain that occurs when he walks and diminishes when he rests. The nurse recognizes that this patient is experiencing intermittent claudication.
What should the nurse suspect from this finding?
A) The patient's venous return from dependent body parts is insufficient.
B) The patient has arterial insufficiency to his lower extremities.
C) The patient is experiencing the prodromal symptoms of a myocardial infarction (MI).
D) The patient is at significant risk of deep venous thrombosis or pulmonary embolism.
Question 6The nurse is providing care for a hemodynamically unstable patient in a critical care setting.
The nurse has read in the patient's chart that his most recent echocardiogram prior to admission indicated a low stroke volume, which the nurse recognizes as being a function of preload, afterload, and contractility. Which of the following statements best describes afterload?
A) The pressure that the ventricles exert on the atria after the conclusion of systole
B) The mean arterial pressure during diastole
C) The quantity of blood that remains in the ventricle at the end of systole
D) The amount of resistance to the ejection of blood from the ventricle
Question 7For which of the following reasons are emergencies in older persons particularly problematic? (Select all that apply.)
A) They occur frequently because of the age-related changes that lower resistance and make the body more susceptible to injury and illness.
B) They are not as urgent as it is expected that elderly people will die.
C) They often present an atypical picture that complicates diagnosis.
D) They can be more difficult to treat or stabilize because of older persons' altered response to treatment.
E) They carry a greater risk of causing serious complications and death.
